Return back to Identity Server if ADFS User Login fails

[vkalpana09]

I have the IdentityServer4 connected to ADFS and im able to login with right user credentials. I have enabled IWA and i have a secanrio like if the User clicks cancel it should return back to Identity Server application. As of now if i click cancel it just shows me 401 error page with ADFS URL.

 services.AddAuthentication().AddOpenIdConnect("adfs", "ADFS Authentication", options =>
 {
      options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
      options.SignOutScheme = IdentityServerConstants.SignoutScheme;
      options.Authority = "ADFS URL";
      ptions.ClientId = "Client  Id";
      options.ResponseType = "code";
      options.CallbackPath = "/signin-adfs";
      options.SignedOutCallbackPath = "/signout-callback-adfs";
      options.RemoteSignOutPath = "/signout-adfs";
      options.RequireHttpsMetadata = true;
      options.BackchannelHttpHandler = GetHandler();      
       options.ClientSecret = "Client Secret";
       options.SaveTokens = true;
       options.TokenValidationParameters = new TokenValidationParameters
       {
             NameClaimType = "name",
             RoleClaimType = "role"
         };
         options.GetClaimsFromUserInfoEndpoint = true;
 });

I had similar problem with Azure using openId. We handled it using events,

options.Events = new OpenIdConnectEvents { OnRemoteFailure = ctx => { switch (ctx.Failure.Message) { case string error when error.Contains("Error message which is received"): ctx.HandleResponse(); ctx.Response.Redirect("your page") } } };
